hi
in this figure, what is the seen impedance in x point by M4T mosfet?pl. explain how calculate the impedance at this point?
pay attention that M4T is in triode region.
do 4 bottom transistors have role in impedance?
what different is occurred if sources of vp and vm are dissconected?why this connection is used?
thanks
i leave university three years ago, i found in a paper that i had written before to ask this.
i before sending this post i tried to solve it, but i couldn't. i posted this and i find this answer, i don't know what i must say.
